The IR Resource Guide is a tool that can be shared throughout your organization for anyone who will meet with investors to keep consistency with the story. Plus, it gives an extra level of comfort and confidence to those who will interact with investors, but do not do so on a regular basis. This is perfect for store general managers, DC/Plant management, etc.
Remember, investors can gain significant conviction with the story if they meet with the folks who are customer/client facing. It is a huge best practice to be in a position to show off the talent at all levels of the organization.
Take this example and tailor it to your needs.
